If your bank and backpack are full then the item gets deleted, if this isnt the case, you might have sold it accidently. If it never shows up, contact support. Also don't remember where it is, but the place that connects to valley of the titans, the village place in khotan, it has a weapon vendor 45+ for weapons that are pretty close to the best weapons.

kingsile im axel1255 and i just finished the game and i talked to avery but i didnt get my staff is there any way i can get it

The same thing happened to me recently. I completed the "Defeat General Tso" quest and did not get my staff reward after speaking to the Governor in Hamamitsu village. I was not aware that my bag and my bank was full. I contacted support and they told me that there was nothing they could do about it. Most MMOS that I play have an overflow system, or simply does not allow you to turn in a quest if your bag is full so you don't lose your quest reward. I'd also like to point out that when things get lost in other MMOS, the GM's usually put the missing item back in your bag if you submit a ticket.
